Problems solved by technology

[0002] Pine wood is one of the common woods in my country. It has a pine fragrance, light yellow color, clear texture, and can be antibacterial and mildew resistant. However, pine wood is soft and easy to deform and crack. Therefore, maintenance is more complicated, which obviously shortens the service life of pine wood products. , which has also led to a great limitation in the use of pine wood

Embodiment 1

[0019] A treatment method for preventing deformation and cracking of pine, comprising the following steps:

[0020] (1) Cutting: Peel the pine wood section and cut it according to the required size, which is convenient for post-processing, improves processing efficiency, and obtains wood squares;

[0021] (2) One-time freezing: put the wooden square in sodium selenite solution with a weight concentration of 0.2%, soak it at 40°C for 8 hours, take it out, freeze it at -32°C for 6 hours, and then heat and thaw it at 53°C for 3 hours. Promote the penetration of sodium selenite solution into the wooden cube, and obtain a frozen wooden cube;

[0022] (3) Secondary freezing: Spray the sodium selenite solution in step (2) evenly on the primary frozen wood, the spraying amount is 120ml / m 2 , stand at room temperature for 4 hours, and freeze at -43°C for 7 hours to fully combine sodium selenite with pine wood, increase the hardness of pine wood, reduce the moisture absorption capacity...

Embodiment 2

[0030] A treatment method for preventing deformation and cracking of pine, comprising the following steps:

[0031] (1) Cutting: Peel the pine wood section and cut it according to the required size, which is convenient for post-processing, improves processing efficiency, and obtains wood squares;

[0032] (2) One-time freezing: put the wooden square in sodium selenite solution with a weight concentration of 0.3%, soak it at 43°C for 9 hours, take it out, freeze it at -31°C for 6 hours, and then heat and thaw it at 54°C for 3.5 hours. Promote the penetration of sodium selenite solution into the wooden cube, and obtain a frozen wooden cube;

[0033] (3) Secondary freezing: Spray the sodium selenite solution in step (2) evenly on the primary frozen wood, the spraying amount is 130ml / m 2 , stand at room temperature for 4.5 hours, freeze at -42°C for 7.5 hours, fully combine sodium selenite with pine wood, increase the hardness of pine wood, reduce the moisture absorption capacity...

Embodiment 3

[0041] A treatment method for preventing deformation and cracking of pine, comprising the following steps:

[0042] (1) Cutting: Peel the pine wood section and cut it according to the required size, which is convenient for post-processing, improves processing efficiency, and obtains wood squares;

[0043](2) One-time freezing: put the wooden square in sodium selenite solution with a weight concentration of 0.4%, soak it at 45°C for 10 hours, take it out, freeze it at -30°C for 7 hours, and then heat and thaw it at 55°C for 4 hours. Promote the penetration of sodium selenite solution into the wooden cube, and obtain a frozen wooden cube;

[0044] (3) Secondary freezing: Spray the sodium selenite solution in step (2) evenly on the primary frozen wood, the spraying amount is 140ml / m 2 , stand at room temperature for 5 hours, and freeze at -41°C for 8 hours to fully combine sodium selenite with pine wood, increase the hardness of pine wood, reduce the moisture absorption capacity...

Abstract

The invention mainly relates to the technical field of wood product machining, and discloses a treatment method for preventing pine wood deformation cracking. The treatment method includes the steps of cutting, primary freezing, secondary freezing, stabilization and drying; the method is simple, operation is facilitated, the pine wood strength and stability are obviously increased, pine wood deformation cracking is prevented, the using value of pine wood is improved, and the economic income is increased by 14.8%; pine wood sections are cut after peel is removed, and therefore even treatment in the later period is facilitated, and the treatment efficiency is improved; battens obtained after cutting are soaked into a sodium selenite solution, the sodium selenite solution is promoted to permeate into the battens, the combining capacity of lignin and hemicelluloses in the pine wood to celluloses is improved, and pine wood deformation is restrained; slow freezing and quick dissolution are sequentially carried out after soaking, and quick freezing and slow dissolution are sequentially carried out after the sodium selenite solution is sprayed, sodium selenite is sufficiently combined with the pine wood, the pine wood hardness is improved, the moisture absorption capacity of the pine wood is reduced, and the pine wood stability is improved.

Description

technical field [0001] The invention mainly relates to the technical field of wood product processing, in particular to a treatment method for preventing deformation and cracking of pine wood. Background technique [0002] Pine wood is one of the common woods in my country. It has a pine fragrance, light yellow color, clear texture, and can be antibacterial and mildew resistant. However, pine wood is soft and easy to deform and crack. Therefore, maintenance is more complicated, which obviously shortens the service life of pine wood products. , which has also led to a great limitation in the use of pine wood. Contents of the invention [0003] In order to make up for the defects of the prior art, the purpose of the present invention is to provide a treatment method for preventing deformation and cracking of pine wood. [0004] A treatment method for preventing deformation and cracking of pine, comprising the following steps: [0005] (1) Cutting: Peel the pine wood section...
